Whirlpool icemaker round plug/flat plug

I have a Whirlpool refrigerator with no icemaker that has the round connector. Someone gave me a new icemaker but of course it has the flat plug. I know they make a universal replacement icemaker that comes with an adapter to use on either type refrigerator. Can anyone tell how that adapter is wired?

The universal ice maker comes with two different cords that just plug onto the ice maker, is not an adaptor. You might be able to call around to your local repair shops to see if some one has some spare flat plug cords lying around. We have several extra of both extra since each universal kit has both of them in the box.

I really fail to see how splicing this round plug ice maker cord will work if he does not have the flat plug cord that will be needed to plug into the back of the freezer compartment?? I understood the ice maker was not in the ref. to get the flat plug cord off of. Guess I miss-undrstood the question.

My guess is that he's gonna decapitate the flat head and splice on the round head. In which case, it's even easier: just match the colors. The icemaker end of each plug that snaps into the back of the module head is the same.
